:SAILING-MACHINE.

Specicaton of Letters Patent.

Patented Mar. 25, 1913.

To all whom may concern.'

Be it known that I, WILLIAM F. WELTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bailing-Machines, of which the following is a specification, ref erence being had therein to the accompanying drawing.

This invention relates to machines for forming and applying wire hails to paper vessels such as oyster pails, ice cream pails, etc., and consists in the matters hereinafter disclosed and then pointed out in the appended claims.

In the accompanying drawings illustrating a practical embodiment of the various features of the invention Figure 1 is a plan view of a machine embodying the same; Fig.'

2 is a front elevation of the machine of Fig. 1; Fig. 3 is a detail view showing the front of the wire gripping mechanism and the bail stripping mechanism; Fig. 4 is a detail view showing the pail-block with a pail thereon and certain of the parts shown in Fig. 3; Fig. 5 is a detail view of the part-s shown in Fig. 4 with certain of the parts in section; Fig. 6 is a detail view of the rear of the wire holder; Fig. 7 is a detail view partly in section showing the brake to cushion the wire-bending and driving devices; Fig. 8 is a detail view partly in section showing the staple clenching means in the form block with a pail and bail thereon; and Fig. 9 is a detail view partly in section showing the interior of the form block.

The operating mechanism is `suitably mounted and secured on the horizontal table 10, supported by suitable standards or legs 11 and having bearings 12 at its rear end for the main driving shaft 13 of the machine which is driven by a pulley 14 from suitable power. The shaft 13 carries a bevel gear 15 which meshes with a bevel gear 16 on a counter shaft 17, journaled in suitable supports on one side of the top 0f t-he table and carrying a crank-arm 18 which is coupled by a slotted connection to a connecting link 19 pivoted to the inner end of the gripper jaw 20, which is pivoted on a carrier 21 sliding on a fixed track 22 and having a fixed gripper 23 with which the movable jaw coperates to grip the wire m fed through the straightening rollers 24. The wire extends inwardly beyond the rolls and beyond a holder secured on the table to prevent the free end of the wire being displaced out of the path of the grippers by the retraction of the cutting plunger. This h older is shown in detail in Fig. 6 and conslsts of a plate 25 secured upon the inner face of the block 26 in such manner as to allow the wire to pass between these parts. The block is adjustably mounted in a guideway 27 in the rear face of an upright 28 on the table, and is adjustably set by the headed bolts or lag screws 29 in position so that the wire is severed against its end by the cutting plunger 30. When this plunger 30 is retracted it has a tendency to bend the end of the wire back or away from the block and out of the path of the grippers, and the holder prevents this bending of the wire and retains its end in position for the grippers. When the arm 18 is in the position shown in Fig. 3 the grippers 20 and 23 are in position to engage the end of the wire and as shaft 17 continues to revolve the draft of thel connecting link 19 on the inner end of the jaw 2() firmly clamps the wire between the grippers, and as the arm 18 rotates the wire isv drawn through its rolls across the machine in the rear of the form block 31, upon which the pail or bucket to be bailed is placed in inverted lposition, and also in the rear of the bail block 40 upon which the wire is formed into bails. As soon as the arm commences its return movement, the push of the arm on the connecting link 19 causes the jaw 20 to open and release the wire, at which time the bail-holding plate, the bail-forming plungers, and the cutting plunger lto sever the wire, are moved to hold, cut olf, and bend the wire into bail form to bring the ends of the wire int-o position to be acted upon by the mechanism to form` the staples of the bail and to insert and clench the same within the walls of the vessel to be bailed.

Standards 32 on the table carry a reciprocating plate 33 which carries bail-forming plungers 34 in suitable recesses along the side edges of the plate, these plungers being secured adjustably on the plate by the set screws 35 and forming the bending plungers for the bail. The plate 33 also carries in a suitable dove-tailed groove the slide 36, adjustably connected to a plate 37 by the set screw 38 and sliding independently of the plate 33. The slide 36 is provided with two short ears 39 each provided with a V-shaped groove in its end as shown in dotted lines in Fig. 1. On the table between the form block and the plate 36 is a vertical bailblock 40 provided with two slots 41 in line with the ears 39 on the slide 36, as shown in Fig. 1, and the ears 39 coperating with the slots 41 in the plate 40 to hold the wire during the bending operation by the plungers 34. The plate 33 carries the cuttingplunger 30 adjustable on its side by the set screws 42, and when the plate 33 is actuated the plunger will be carried forward to bring its angular cutting end against the wire and sever the same against the block 26. The plate 33 is actuated by the engagement of a roller 43 on its inner end with an eccentric groove 44 in the cam disk 45, mounted on the main driving shaft 13. The disk 45 is also provided with a cam surface 46, which engages with a roller 47 on the inner end of the slide plate 37. The action of these cams is timed so that the holding plate 36, the bending plungers 34, and the cutting plunger 30 move forward just as the wire is released by the grippers, after it is drawn across the machine. The shaft 13 carries a cam-wheel 48 which is provided with an eccentric groove (not shown) actuating a roller in a manner now well understood in the art carried on the upper end of a connecting rod 49, coupled to an arm 50 on a rock-shaft 51 journaled in suitable hangers 52 depending from the table 10J This shaft 51 extends from the rear to the fro-nt of the machine, and carries on its forward end as shown in Fig. 2 a lever 53 the ends of which are connected on each side of the links 54 with the levers 55 and 56 respectively pivoted xon brackets 57 at each side of the table and whose upper ends are coupled to the reciprocating blocks 58 which carry the staple forming and driving devices arranged on each side of the form block 31 to insert a staple or end of a bail in each side of the pail or bucket. These blocks slide on rods 59 secured on frames 60 mounted on the table, and the blocks carry plates 61 upon which the staple benders and drivers slide and are guided between the flanges 62. The. staple bending and driving devices are of any suitable form and construction and so need not to be herein specifically described beyond stating that they comprise the usual die plates 63 around which the ends of the bail are bent, and the bending plates 64 and driving plates 65 for the staples fo-rmed at the ends of the bail. The movement of the levers 56 carries forward the blocks and the plates 64 and 65, and as the plates 64 extend in advance of the plates 65 they give the ends of the wire, which is bent into bail-form on block 40 by the plungers 34, a short right-angle bend against the die plates 63 to form t-he staples, and as soon as the staples or end-bends are made the plates 64 stop and the plates 65 continue to advance and drive the staples thus formed through the pail y at the same time that the die plates 63 are withdrawn to permit this action. The bail comprises the handle portion e and the end staples z, and in order to clench the staples when driven through the pail suitable clenching devices are provided, as shown in Figs. 1, 2 and 8. As shown in Fig. 9 the lower portion of the form block 31 has a chamber 66 for levers 67 connected at one end with a slide 68 which is coupled at its rear end with the lower end of a lever 69 pivoted on a support on the table and having a roller 70 at its upper end engaged by a cam 71 mounted on the shaft 13 so that the slide may be shifted rearwardly at the proper moment by the action of the cam. The slide is returned to its normal position by a coiled spring (not shown) connected between the frame and slide.

The form block carries the vertical rockshafts 72 connected by links 73 at their lower ends to the levers 67, and provided at. their upper ends with clenching plates 74 working in an upper recess or chamber 75 of the block in line with the driving plates 65. The cam 71 on the main driving shaft 13 is timed to shift the clenching plates from the position shown in Fig. 2 to the position shown in Fig. 8, just as the ends of the bail forming the staples have been driven through t-he pail by the drivers 65. The stapling devices are cushioned so as not to strike the wire against the material of the pail hard enough` to injure or deface it by driving the sides of the bail more or less into the material by means of a brake which in the present form consists of a brake-band 76 inthe form of a split-ring surrounding a leather covered disk 77 on the shaft 51, the brake being secured in place by a bracket 78 depending from the understide of the table 10 and being adjusted by means of a nut 79 threaded on a depending screw 80. The effectiveness of the stroke of the drivers to insert the staples and bend them over on the clenchers is not affected by the cushion, but the blow of the stroke is rendered softer so as not to damage the paper of the pails.

The carrier 21 is provided with a cam plate 80 to release or strip the bail from the lbail-block 40; at each forward movement of the carrier t-he cam plate 80 passes under the body portion of the previously formed bail and lifts it to the position shown in Fig. 5 free of the bail-block so that the pail or vessel may be easily removed from the form-block.

In order to prevent the chamber 75 being clogged or filled by the particles of paperstock carried into it by the staples in passlng through the sides of the pail, I provide a discharge chute 81 in the form block leading down from the center of the' chamber 7 5 to discharge at one side of the block. The movement of the plates 7 4 tends to move the particles of paper toward the center of the chamber to the outlet.

ln the operation of the machine, the pail or, vessel y to be bailed is placed in inverted position over the form block, and when the machine is set in operation the grippers grasp the end of the wire and draw it forward across the machine in the rear of the form block and bail block. When the grippers release the wire, the cams on the driving shaft carry forward the slide 36 to grasp and hold the wire against the bail block, and the plate 33 which carries the cutting plunger 30 to cut off the wire and the bailforming plungers 34 to bend the bail around the bail block and bring its ends into position on the die plates 63. The staple formers and drivers then advance and the plates 64: form a right-angle bend in each end of the wire, and the driving plates 63 then continue to advance as the plates 64: are released and drive the staples through the bail and against the clenching plates which with this movement are shifted by the slide 68 to position to coperate with the drivers to clench the staples in place. The return of the gripper carrier to its position to again grasp the end of the wire causes the cam plate 8O to stri the bail from the block 40, when the comp eted pail or vessel is easily removed and another one placed in position for repetition of the work.
